To all whom/it may concern." I

Be it known that I, ELAM H. DAVIS, 21 citi: Zen of the United States,and a resident of Memphis, in the county of Shelby and State ofTennessee, have invented a certain new and useful Improvement inAutomobile- Wheel Rims, of which the following'is a specification.

One of the principal objects of my invention is to provide an improvedrim for 1110- tor vehicle wheels using pneumatic tires, which, will,while effectually retaining the tire in place on the wheel, allow ofquick and ready dismounting of the tire with minimum efiort and withoutthe employment of any specialslrill or the use of special tools.

.Another object of the invention contemplates the provision of a rimconsisting of a fixed telly-carried section and a removable section andinterlocking means carried by the folly and by the removable sec-,'

tion and through the operation of which the removable section mayquickly and easily be mounted. in place on the telly for c0- acting withthe fixed section in retaining the tire on the wheel,v means. of novelnature being provided for securing the removable section againstaccidental displacement.

Auturther object of my invention is to provide an improved rim of theclass described which will be extremely simple, con- Sisting of aminimum number of parts, and which will be durable, efficient in operation, and inexpensive to manufacture.

With these andpther objects in view which will become apparent as thedescription proceeds, construction, combination, and arrangement ofparts hereinafter more fully described and claimed, and illustrated inthe accompanying drawing in which like characters 'of reference indicatelike parts throughout the several figures, of which- Figure 1 representsa View in elevation of a wheel equipped with a rim constructed accordingto my invention, parts of the rim being broken away to better illustratethe Fig. 2 shows a fragmentary viewin eleyation of a portion of the rim,the retaining bolt and bolt lock being shown partly in section.

"Fig. 3 represents a view in section taken on the plane indicated by theline 33 of FignQ.

the invention resides in the Fig. 1.

Fig. 9 represents :1 sectional view taken on the plane indicated by theline'9 9 of F ig. 1.

Fig. 10 represents a view in section taken on the plane indicated by theline 1010 of Fig. 9, and

Fig. 11 represents a plan view of the fcllycarried plate with which theretaining bolts engage.

Referring more particularly to the drawings, at 5 is indicated generallyan automobile Wheel of ordinary construction, and at 6 is indicated thefolly thereof. On this folly the rim which forms the subject of myinvention is mounted.

The rim includes a fixed or stationary section A carried by the telly.an annular ring B carried by the telly, and a detachable annular outersection or removable sec 7 and 8 is the hook flange 9 for engagementwith one of the hook-shaped, bends formed at the base of a tire casing".

The annular flat ring B fits againstthe opposite face of the telly fromthat against which the flange 8 of section A lids, and the periphery ofring B extends slightly beyond the periphery of the felly. The flange 7of section A is of a width slightly less than the width of the felly 6,so that a space 10 occurs between the ring B and the adjacent edge offlange 7. The section A. and ring B are secured to the telly by a'llurality of bolts 11 which extend through the ring B, telly 6. andflange 8 of section A. the heads 12 of the bolts being countersunk inthe ring. The outer ends of the bolts which extend through the flange 8are threaded for receiving nuts 13 whereby the bolts may be tightened inplace.

The removable section C is in. the nature of an annular ring which, whenthe section is-in place, fits against the ring B. The section C isequipped with a hook flange 14 adapted to engage the bead on the base ofthe tire casing opposite the one which is engaged by the hook flange'Qof section The section C may be stamped out ofsuitable metal, and thissection is provided at spaced intervals along the base of the hookedflange 14 with inwardly extending segments 15 equipped each with adownwardly extending flange gr edge 16. These segments may be suita lywelded in place upon the removable sec ion C. The segments 15 areadapted to coact with wedges 17 formed on the periphery of the ring B,in securing ltlhe e. y.

removable section C in place upon the The wedges 17 *may be formedintegrally with ring B or may be Welded in place thereon. At thenarrower ends of the wedges 17 the peripheral portion of the ring B isrecessed as at 18 to allow the introduction of the downturned edges 16of segrnent.-15 into the space '10 occurring between the ring'B andadjacent edge of flange 7.- -VVhen the section C has thus been, placed ast the ring vB with the downturned .e ges of the segments occurring insaid L rounded as indicated at 21.

space 10, a, partial. twist or turn of the section (3 in a direction tomove the segments toward the wedges, will tighten the sectidn C in placeon the folly, since the action of the inclined inner edges 19 of thewedges against the downturned edges of the segments, will draw thesection C tightly against the rin B and will eiiectively wedge itinplace. he inner face of the section C is recessed circumferentially asat 20, so that the area of the section which frictionally engages aainst the ring 3 is thus greatly diminished. When the removable sectionis in place as indicated in Fig. 8, the upper faces of the segments 15are, as will be noted, flush with the outer face of the flange 7 ofsection A. In order that there will be no danger of the material of thetire casing being out or caught between the segments and the adjacentedge of flange 7 the corners of said segments and flange are In orderthat the removable section may be retained in place and held againstaccidental reverse movement which might tend to loosen it, I provide oneor more retaining bolts 22 which are adapted, when the ring has beenturned intowedging position, to be passed through registering openingsin the section and ring, through a bore provided in the folly 6, and tobe turned into engagement with the threaded portions of a bore oropening provided in a plate 23 countersunk 1n the telly. The inner endof the bolt, as indicated in Figs. 9 and 10, is reduced on oppositesides; the remaining portions of the bolt end being threaded as at 24.The opening in the plate 23 is, as indicated in Fig. 11, provideddiametrically opposed points with instanding threads 25 adapted to beengaged by the threads 24 of the bolt 22, when the latter is moved aquarter revolution. Thus, as will be evident, the bolt may quickly betightened in place by simply turning it through one quarter of arevolution. The plate 23 may be secured in place by. means of screws 26or other suitable fastening elements, said plate being set in arecessprovided in the face of the folly 6 beneath the fish e 8. The bolt22 is equipped, beneath its read 27, with a washer 28 which restsagainst the outer face of the removable section 0, and beneath thewasher the bolt is enlarged as at 29, said en- I have provided a meansfor securing or locking the bolt 22 in position, and this means is inthenature of a cam or eccentric 30 formed on the rivet 31 carried by thesection C adjacent" the opening through which the bolt 22 extends, saidrivet being provided with a head 32 whereby it may be forcibly turnedslightly in one direction or another. The cam, in locking the bolt, isadapted to be turned whereby to engage in a recess at 33 cut in the bolthead 27 just outside of the washer 28, as indicated in Figs. 2 and 3.When the cam has thus been turned so as to engage within the recess inthe bolt head, the latter will be prevented from turning in eitherdirection, so that an efiective lock for the bolt is thus providedl The.rivet 31 is secured tightly in place on the removable section C, sothat a considerable force must be applied to the head 32 before the cammay be moved in one direction or another, and therefore there will be nodanger of the cam jarring out of engagement with the bolt head 27. Asuitable washer indicated at 34 in Fig. 3, may be arranged between thecam 30 and the adjacent face of section C.

As indicated clearly in Fig. 1, the felly 6 and flange 7 of section Aare recessed laterally from the outer Side of the wheel to the centerthereof as indicated at 35, whereby to readily receive the valve of thetire tube. In order that the valve may be retamed positively in placeafter the tire has been placed upon the rim, a filler block 36 isI'OVldGd which block is adapted to slide aterally into the recess tofill up that portion thereof not occupied by the valve. The blocknt itsinner end isprovided with an arcuate cutaway portion 37 conforming withthe curvature of the valve. The ring B is split at a point registeringwith the recess incense and proportioned as torest at its outer endflush with the outer face of the ring when said block is in position. Inorder that the adjacent ends of'the ring B may be held against spreadingthe outer end of the block 36 is equipped with laterally extendingdove-- telly and the tire removed, theililler block Y tours as well asrofessionals. -Fnrthermore, an exceedmg' y small space of time s.

being of course slipped outbefore the tire is drawn oil of the rim.

No special skill is requiredin securing the section in place or inremoving the same, so that the rim may be readily operated by amareqmredin mounting or dismounting. the re-- movable'section, and no specialtools are necessary, .an ordinary sized wrench being the only tool whichis brought into play. When the rim section is in'place it is heldtightly and solidly onto the telly, and presents such a tight joint thatno moisture or foreign matter may enter beneath the inner tube of thetire, so that the latterwill be completely protected.

Although I have describedthe preferred embodiment of my invention, 1 maydesire to make such changes in the construction, combination, andarrangement of I parts thereof, as do not depart from the spirit of theinvention and the scope of the appended claims.

The removable section of the rim is provided at one or more points onits outer face with lugs or projections 39 which may be tapped by a toolin disngaging'the coacting locking means between the section and. ringor in finally shifting the outer section into locking position.
